Problems solved by technology
However, if the method of removing or isolating the shorting bar by laser is used, the cost is high, and if the thin film collective tube switch is used, the uniformity of the thin film transistor is required to be high, and the signal line cannot be detected by using the shorting bar to detect the display panel In addition, in the method of using a shorting bar, if the shorting bar is defective, the normal display panel will be mistakenly detected as defective

A connector of a display panel detecting device, and a display panel detecting device and method, which can realize the detection of a display panel with small-pitch signal lines without producing a shorting bar, thereby saving costs. The connector of a display panel detecting device comprises: a supporting part (32); a contact part (33) fixedly connected to the supporting part (32), wherein the contact part (33) has a strip-shaped contact surface which is used to simultaneously contact a plurality of signal line terminals on the display panel; and a signal transmission part (34), wherein one end of the signal transmission part is connected to the contact part (33), and the other end thereof is used for connecting to a detection signal generator of the display panel detecting device. The display panel detecting device comprises: the detection signal generator; and at least one connector of the display panel detecting device, wherein the connector is electrically connected to the detection signal generator through the signal transmission part (34). The display panel detecting method comprises: placing the connector in a fan-out area on the perimeter of the display panel, so as to enable the contact surface to simultaneously contact a plurality of signal line terminals; and providing a detection signal to the signal lines by means of the connector.
Description
technical field [0001] The invention relates to the field of display technology, in particular to a connection head of a display panel detection device, a display panel detection device and a method. Background technique [0002] At present, in the production process of the display panel, before the driver IC is bound, the display substrate or the display panel after the substrate is boxed needs to be electrically tested, that is, the signal is input from the signal line terminal of the display panel to the display panel through the testing equipment, so that It can detect the defect of the display panel, prevent the defect from being discovered after the driver IC binding process, reduce the waste of the driver IC, and get the defect information faster, and feed it back to the previous process, so that the cause of the defect can be found earlier. [0003] In the existing detection process of the display board, such as figure 1 As shown, probe 1 is directly connected to te...
